I can easily buy a tapwater purifier if needed to change PH before water changes as no way going to use chemicals to lower ph.
Is 8.0 to high for fire mouths to breed ?
Ideal temps?
Thank you

Hello Bianca and welcome to fishlore.

I also love the CA Firemouth cichlids. I do not have a pair, just one juvi growing out in a 29g tank. My PH is very low so have not had any problems with it (yet). But after doing research, I find on the average that the Ph range is from 7.0-8. Depends on what site you read. But I was surprised to see that during breeding, the higher Ph is what works. So I can assume that your Ph of 8 will be fine for your firemouth.
They like a higher temperature as well. I would think that around 80* is the normal range, and higher during spawning.
I agree with not messing with your PH, that alone will cause you more problems with them then you need.
IMO your PH is good enough and will not cause any problems that need to be addressed with modifying your PH levels. They are a pretty hardy fish but really need clean water conditions the most over ideal PH range.
Good luck with your choice...
